It is true, though I understand Micropore do not advertise this as it could encourage irresponsible behaviour.

The reason is the CaOH is very well fixed in the plastic matrix in the EAC, but in granules it is in a base that falls apart in water.

With sorb, within 30 seconds of it being wet, it has given up enough of its active components to increase the pH of the water from 7 to 13. With an EAC, there is almost no change in 30 seconds, and it takes over 30 minutes to get to 13. This means that so long as the flood does not last more than 5 to 10 minutes, you can flush it out and it still keeps running.

The EAC restarts very quickly indeed.
